Tracking information shows that the device was delivered to conmed; however, the device was unable to be located for evaluation.Based on the evaluation, by r&d engineering, of the provided photographs, the ceramic insulator fractured and has missing fragments.The ceramic appears to have fractured due to mechanical load, perhaps due to impact or being forced against another object such as a scope or cannula.The manufacturing documents from the device history record have been reviewed with special attention to the manufacturing and inspection of the product.The product released for distribution was found to have met all specifications prior to shipment.This is the only complaint for this lot number and failure mode within the past two years.A two-year review of complaint history revealed there has been a total of 6 complaints, regarding 7 devices, for this device family and failure mode.During this same time frame (b)(4) devices have been manufactured and shipped worldwide.Should all the complaint devices have been found confirmed for this reported failure, the rate of failure would be 0.0002.Per the instructions for use, the user is advised the following: warnings: electrodes must only be used in a conductive fluid medium to avoid insulation damage.If any visual defects are noticed in the insulation, or the ceramic/insulation is damaged in any way, stop using the device immediately and replace the device.Use ablators only within prescribed generator settings.High power generator settings, and prolonged use, may result in damage to the insulation, melting of the electrode tip or increased risk of patient burns.Do not bury electrode tip and insulator in tissue.The electrode tip must be completely surrounded by conductive fluid when activated in order to avoid damage to the insulation.Do not pry or pull tissue using the device.Insulation may be damaged.This issue will continue to be monitored through the complaint system to assure patient safety.
